- Description
- This is a SOURCES SOUGHT NOTICE for market research purposes. THIS IS NOT A REQUEST FOR PROPOSALS. Accurate flowmeters are required for dispensers that sell gaseous fuels for use in vehicles. In a hydrogen gas dispenser, a compressor uses gas from a low pressure source to fill a set of pressure vessels (a cascade tube bank). Valves are sequentially opened to allow gas to flow from each cascade tube to the vehicle tank. As each tube is opened, surges of flow and pressure occur at the flowmeter in the dispenser. Wide temperature changes also occur at the flowmeter and totalized flow errors as large as 10 % have been reported. Another arrangement for refueling gas powered vehicles is direct compression with a reciprocating compressor that generates pulsatile flow at approximately 2 Hz creating a transient flow measurement problem at the billing meter. The National Institute of Standards and Technology is performing tests on coriolis flowmeters. NIST is contemplating purchasing coriolis flowmeters from various manufacturers to perform testing. The coriolis flowmeters will be tested in a system that generates transient flow conditions that simulate those occurring in dispensers used to fill cars with gaseous fuels, such as natural gas or hydrogen. For safety reasons, only simulants of the gaseous fuels (helium or nitrogen) will be used in the transient experiments, but the meter must handle 40 MPa pressures and have fast time response (<0.2 s). The totalized flow from the coriolis meters will be compared to a reference value calculated from a flow standard. To be considered for the testing, coriolis flowmeters must meet the following required specifications: -Must measure gaseous nitrogen or helium and must have a full scale flow of at least 1.2 kg/min but no more than 2 kg/min; -Must use a coriolis flow measurement method and be an existing product design (i.e. not a prototype); -Must have a maximum pressure capability of 40 MPa; -Must accept temperatures from -45 °C to +45 °C; -The flowmeter must have accuracy of <1% of reading zero stability over a range of 10% to 100% of its full scale flow; -Must have a response time of <0.2 seconds; -Must have NPT female, Swagelok VCO, or cone and thread inlet and outlet connections; -Must have a 4 to 20 mA and frequency (pulse) outputs. NIST is seeking responses from all responsible sources, including large, foreign, and small businesses. Small businesses are defined under the associated NAICS code for this effort, 334519, as those domestic sources having 500 employees or less. Please include your company’s size classification in any response to this notice. Companies that manufacture coriolis flowmeters, meeting the above referenced specifications, are requested to e-mail product literature and a letter describing their abilities to carol.wood@nist.gov no later than the response date for this sources sought notice. The letter should include achievable specifications and any other information relevant to your product or capabilities. Also, the following information is requested to be provided as part of the response to this sources sought notice: 1. Name and business size of the company that manufactures the flowmeters for which specifications are provided; 2. Name of company(ies) that are authorized to sell the flowmeters, their addresses, and a point of contact for the company (name, phone number, fax number and email address); 3. Indication of number of days, after receipt of order that is typical for delivery of such flowmeters; 4. Indication of whether each instrument (including installation) for which specifications are sent to carol.wood@nist.gov are currently on one or more GSA Federal Supply Schedule contracts and, if so, the GSA FSS contract number(s); 5. Any other relevant information that is not listed above which the Government should consider in finalizing its market research. All documentation must be sent to Carol A. Wood, Contract Specialist, at the National Institute of Standards and Technology, Acquisition Management Division, 100 Bureau Drive, Mail Stop 1640, Gaithersburg, MD 20899-1640. E-mail address: CAROL.WOOD@NIST.GOV. Submission must be received not later than 3:00 PM local time on February 15, 2010.
